Abstract
A fluid flow control device includes a regulator for operating at high pressures and an integral bypass valve. The regulator and the bypass valve each include a control assembly that is movable between an open position and a closed position. The regulator and bypass valves are biased into the open positions and adapted to move into the closed positions when an operating pressure rises to above respective regulator and bypass set-point pressures. The bypass set-point pressure is lower than the regulator set-point pressure such that when the operating pressure rises above the bypass set-point pressure, the bypass valve automatically closes and allows the regulator to perform under normal operating conditions. So configured, the bypass valve is arranged to accommodate at least some of the fluid flow through the system until the operating pressure reaches the normal operating pressure, which is somewhere between the bypass and regulator set-point pressures.
